Environmentally Sealed Pushbuttons Series WB

Distinctive Characteristics

Single unit construction of the bushing and case gives added

protection from environmental elements.

Specially designed contact mechanism for breaking light welds.

Minimal contact bounce is achieved with specially

designed interlocked switching mechanism.

Outer housing of heat resistant resin meets UL 94V-0

ﬂammability standard and provides high arc and

tracking resistance.

Solder lug and screw terminal models meet IP67 of

IEC60529 Standards at front panel (dust tight and

water protected for temporary immersion). Behind

panel standard is IP60 (dust tight but not water protected).

Wire lead models conform fully to IP67 of IEC60529 Standards

at front and behind panel (dust tight and water protected for

temporary immersion). These models are epoxy sealed at the

switch base and covered by an outer case for further protection

from dust and water (not operable under water).
